ing pressure about the periphery of the cover and container.

A'further object of the invention is'to seal the cover in place against unauthorized removal.

Other objects and advantages of my invention will become more apparent from the following description of an embodiment thereof, reference being` made to the accompanying drawing in which like reference charactersare employed to designate like parts throughout the same.

In the drawingy Fig. 1 is a top plan view of an embodiment of my invention, showing the cover on the receptacle in iuid tight sealed relation.

Fig. 2 is an enlarged fragmentary section I taken on line 2 2 of'Fig. 1.

Fig. 3 is a fragmentary plan view of the lockingor clamping ring contracted to seal the cover on the receptacle. Y

Fig. 4 is a view similar to Fig. 3 except that the ring is shown partly expanded as in removing the ring and cover from the recep-i tacle.

Fig. 5 is a section taken on line 5-55 of Fig. 4.

Fig. 6 is an elevation of the lockin or clamping ring looking in the direction o the arrows in Fig. 3.

My invention is particularly applicable to metallic containers or receptacles such as barrels or drums and the like, which are provided with a circumferential bead at their open ends for supporting a cover andl for reinforcement purposes.

betweenV Another. obi ect of my invention is to insure a fiuid tight seal between the cover and the; receptacle by uniformly distributing the seal- Referring to the drawing, in which I have illustrated an embodiment of my invention, the barrel or drum is indicated atl. The upper edge ofthe container is rolled to form a peripheral'bead 2 at the open end thereof. A cover 3 comprising a cupped member having aperiiheral upwardly and outwardly extend- Iing ange 4, is supported by the bead 2 in such a manner that the cupped portion ofthe cover may be telescoped for a short distance withinA 6? the container, as illustrated in Fig. 2. It will be noted that a portion of the lange 4 is slightly arcuate in cross section to conform with the approximate curvature of the upper surface ofthe bead, and that the outer edge 55.

. of theiange terminates at a oint near that defned' the greatest outer iameter of the bead. though I have shown the {iange ex-v tending to apoint equal to the greatest outer diameter of the bead, I nd that the flange may extend to'a point just short thereof, it being sufficient that the ange extend completel over the packing 5 between the ange and t e bead. lhe packing may consist of an annulus of an sultable packing material, 7F and I have found that an annulus of flexibleV rubber tubing is very satisfactory for this purpose.

I have provided a. simple means for removably securing .the cover on the receptacle vto eiect a iiuid tight seal between the'same by exerting a substantially uniform pressure on the cover and the bead in a direction substantially arallel to the axis of the container.

In t e present embodiment this means inv85' cludes a split contractible .channeled clamping rin 6 substantially U-sha ed in cross section. `e u per' and lower ange and bead engaging wa s respectively of the ring extend insubstantially parallel lanes only near split ring and may be formed integrally with 10 v i thering or formed separately and welded to tab 12 secured to the ring, for the purposev of sealing the lever in locked position against unauthorized movement.

A pair of links 13 and 14 are pivotally connected at one end by means of the pin 10 to the lug 8, the opposite ends of the links being pivotally connected to thel lever 11 by means of a pin 15. It will be noted that the links are each offset slightly to permit free movement about the lug 7 when the lever is operated. It is preferred that the pin 15 be so located on the lever 11 that it will lie behind a line drawn through the respective pins 9 and 10 when the lever is moved to the position shown in Fig. 1. In this manner movement of the lever 11 to the extreme position shown in Fig. 1 will permit the pin 15 to pass the dead center line of the pins 9 and 10, thereby preventing accidental release of the lever under stresses set up by the contracted ring.

Referring more particularly to Figs. 3, 4 and 5, I have illustrated a means for exerting a lateral pressure between the ring and the sidewall of the cover. This means includes an extension 16 of the lever 11, the end of this extension being bent slightly upwardly as as 17 in Fig. 5, forming a shoe for engaging the adjacent wall of the cover. The extension 16 is of sufficient length to engage the cover side wall under considerable lateral pressure and to cause the ring 6 to be tightly contracted about the bead'and flange to press the same tightly together when the lever 11 is moved to the position in Fig. l, thereby uniformly exerting and distributing the sealing pressure between the flange and the bead.

In Fig. 4 I have shown the lever 11 and the ring 6 in partly opened position to allow the ring to assume its normal open position and to release lateral pressure on the cover side wall and ring. By further moving the lever to the right in Fig. 4, the ring may be expanded to a point where its circumference. is greater than that of the flange or bead to permit its removal from the receptacle. In this manner the cover and packing ring may be lifted from the receptacle to permit cleaning the latter, or for emptying or filling the same.

It will be noted that the parts comprising the ring contracting means, that is, the lever 11 and the links 13 and 14 are arranged so that the stresses applied in contracting the ring 6 are exerted through this means as a unit on opposite sides of the lugs or the upper wall of the channeled ring. In this manner, greater stresses may be applied and a tighter seal obtained without danger of distorting the lugs or pulling them loose.

It is to be understood that while I have shown my invention applied to receptacles having openings of the same diameter as the inner diameter of the receptacle, the invention is equally applicable to receptacles having restricted openings.

It-will also be observed that by my invention the full removable cover may be clamped easily on the receptacle in fluid sealing contact and may be removed easily without the aid of tools.

In my copending applications Serial Numbers 423,333, 423,334, and 423,335 all filed Jan. 25, 1930, I have disclosed several other types of closures for metallic receptacles.
